NEW JERSEY, A CORPORATION OF N EJV JERSEY MACHINE FOR USE IN THE MANUFACTURE OF SHOES 7 Application filed December 29, 1930.

This invention relates to machines for use in the manufacture'of shoes and the machine herein shown and described, for the purpose of illustrating one embodiment of the invention, is particularly designed for operating on shoes the uppers of which are provided with flanges to which soles may be secured.

Machines of the type disclosed in United States Letters Patent No. 1,720,212, granted July 9, 1929, on my application, are in successful use to secure together the sole-attaching flanges of uppers and the inarginsof soles, the sole-attaching flanges of the uppers or the marginal portions of the soles or both having been previously coated with cement.

In the operation of machines of the type referred to, the upper is worked progressively over a last, the outturned sole-attaching flange of the upper being tucked into the angle betwen the side of the last and the projecting marginal portion of the sole and pressed against the sole to cause the upper and sole toadhere. In making certain types of shoes, however, such for example as those made in accordance with the method disclosed in United States Letters Patent No. 1,230,954, granted June 26, 1917, on application of Charles Tweedie, it is desirable to secure the sole-attaching flange of the upper to the sole without the use of a last. Shoes of the type disclosed in the Letters Patent referred to just above are known in the trade as prewelted shoes. The present invention, however, is not limited in its application to prewelted shoes but may be applied to any type of shoes wherein the uppers have soleattaching flanges which act to secure the uppers to the soles. V

An object of this invention, accordingly, is to provide a machine for pressing together a sole and an outwardly directedsole-attaching flange of an upper, in the operation of which the use of a, last may be dispensed with,

and particularly to provide a machine for effecting adhesion between the welts and soles of prewelted shoes while oif the last. To this end one featureof the invention resides in a machine having a tool for progressively engaging successlve portions of the Serial No. seaasa sole attaching flange of an upper, for example, a welt attached to an upper, a work support for engaging a shoe sole, means for forcing the upper toward the tool, andmeans for eflecting relative movement between the tool and support to press the flange and sole together. In the illustrated machine a tool-having an inclined edgefor engaging the upper surface of a welt, a work support movable to press the sole against the welt, and a roll mounted. on a horn and engaging the inside of the shoe cooperate to eifect progressively the attachment of the upper and sole of a prewelt shoe by cement.

Another feature of the invention consists in a machine for operating on shoes provided ortion thereof to the operating instrumeni alities of the machine. In the illustrated machine means is provided for gripping a por-' tion of the work already operated upon, such as the projecting edge portion of the shoe, that is, the outer marginal portions of the welt and sole, and means for moving said gripping means intermittently to feed the shoe past the operating instrumentalities. In the illustrated machine, the gripping means comprises a vertically fixed upper jaw the lower face of which is parallel to that of the tool and a vertically the sole-engaging face of which is parallel to the upper surface of the sole support. As illustrated the machine is so organized and operated that the jaws grip the shoe when the work support is lowered and are moved'in the'direction of feed, that is, in a planeparallel to the plane of the work-engaging faces of the tool and support, to feed the work and present another portion of the work to the operating instrumentalities, during the operation of which the feed'jaws are released and returned toward the operating instrumentalities in position to engage and feed the work again. In the illustrated machine, the feed jaws are normallyclosed by a spring, and the movement of the work support is utilized to move the jaws to feed the work, to

movable lower jaw open them to release the work, and to return them to initial position.

Another feature of the invention is to provide means for preventing premature adhesion of the shoe parts. To this end the illustrated machine is provided with a separating blade which is located in advance of the tool and support and is normally located between the welt and sole to prevent premature adhesion between the surfaces. In the illustrated machine manually operated means is provided for introducing the blade into operative position and for withdrawing it when its use is not desired, as when the operation on a shoe has been nearly completed.

These and other features of the invention will appear morefully from the following description when read in connection with the accompanying drawings and will be pointed out in the appended claims;

In the drawings,

Fig. 2 is a front elevation of the machine;

Fig. 3 is an enlarged view of the head of the machine as shown invFig. 1;

Fig. 4 is an enlarged view of the head of the machine as shown in Fig. 2; and

Fig. 5 is an enlarged detail view of the operating instrumentalities of the machine, showing in section a shoe being operated upon. The drawings represent a machine for effecting progressively the attachment of the welt of a prewelt shoeand its sole by cement. The illustrated machine comprises a column at the upper end of which is secured a bracket 12 which carries a lasting tool 14 having a work engaging face 16 (Fig. 5) inclined at 45 degrees to the vertical and having a beveled outer end adapted to enter the angle between the upper and-welt of a prewelt shoe. The tool 14 carries on its work-engaging face a gage 18 which may relatively to the beveled end of the tool 14. The gage 18 has suliicient extent heightwise of the shoe to engage the edge face of the welt and a portion of the edge face of the sole, there being sufficient space between the gage and the upper face of the work support so thatthe application of pressure by the work support to the sole and welt is not interfered with. The stem 13 of the tool 14 is arcuate and is received in a corresponding recess in the bracket 12. The stem 13 is clamped in adjusted position by a plate 15 and bolts 17 which pass through arcuate slots in the stem 13, through the plate 15 and through the bracket 12, and clamp these parts rigidly together.

A sole support 20 having itssole-receiving face inclined to correspond to the inclination of the tool 14 is provided with a split sleeve 22 which is secured by means of cap screws 24 to the upper end of a post 26. The

be adj usted post 26 is arranged for vertical sliding move-'- ment in bearings 28, 30, in the upper one of which it is splined to prevent rotation. The post 26 carries a shock-absorbing collar 32 which will engage the bearing 28 before the surfaces of the gage 18 and support 20 come into contact, thus forming a stop to limit upward movement of the work support.

The machine is arranged for both manual and power operation. 0n each side of the post 26 is a roll 34 each'of which is engaged by a cam surface 36 formed on a cam member 38. The member 38 is pivoted to the bearings at 40 and has a rearwardly extending arm 42 to which a treadle rod 44 is pivoted at 46, the lower end of the rod 44 being pivoted to an inner treadle 48 at 50. The treadle rod 44 is held in raised position by a spring 51, in which position of the treadle rod the cam member is swung outwardly far enough not to apply upward pressure to the rolls, hen the treadle 48 is depressed, the cam member 38 is swung in under the rolls 34 and acts to raise the rod 26 and causes the support 20 to approach the tool 14. When in this position the cam member 38 positively sustains the work and prevents separation ofthe work and the tool.

The tool 14 (Fig. 5) engages only a portion of the transverse extent of the welt and to press the remaining portion of the welt a roll 52 is provided which has a movement toward the tool 14 with a component of movement toward the support 20. The roll 52 is mounted on the lower end of a horn arm for rotation on an axis perpendicular to the general plane of the shoe-sole-engaging surface of the'support 20. The horn arm 53 is adjustably secured in the eye of an eye-bolt 54 the stem of which is journaled in a bearing 56 formed on one end of a shaft 58. The arm 53 rotates about the axis of the stem of the eye-bolt 54 which is substantiallyin alinement with the axis of the roll 52, and when the arm 53 is rotated the position of the roll 52 relatively to the tool 14 and the support 20 is not changed. The arm 53 is also mounted for rotation about an axis substantially parallel to the sole-engaging surface of the support naled in a bearing 60 which extends perpendicular to the axis formed by the stem of the eye-bolt 54 and is formed in a part of a swinging frame 62. The rear end of the shaft 58 has pinned thereto a stop member 64 having a slot which is engaged by a member 65 secured to an arm 66 on a latch 68 to prevent the lateral swinging movement of the horn arm 53 and the roll 52. The latch 68 is pivoted to the frame 62 at 70 and is normally held in operative position by a spring 72. If it is necessary for any reason to swing the horn arm laterally, it is only necessary to press an arm 7 4 of the latch toward the frame a sufliclent 20. To this end the shaft 58 is jourdistance to throw the latch 65 out 1 of the slot in the stop member 64 and permit lateral swinging movement of the horn arm 53. The stop member 64 is also provided with two projecting lugs which engage the member 65 to limit the lateral swinging movement of the horn 53. From the above description it is apparent that the horn 53 can be swung laterally of the sole support 20 about an axis parallel to the soleengaging face of the support to permit a shoe to be put on or taken all of the horn and that the horn may be rotated about an axis perpendicular to the sole-engaging surface of the support to permit the operator to feed the shoe to the lasting tool and support without interference from the curved horn.

The roll 52 ismoved toward both the tool 14a'nd the support 20 by mechanism which will now be described. The frame 62 carrying the roll. 52 and the horn 53 is pivot-ed at 7 8 to an upwardly and outwardly extending arm 76 secured to tl e bracket 12 of the machine which permits the frame 62 carrying the roll and the horn 53 to be swung toward and away from the tool 14 and the support 20. The frame 02 is caused to swing toward the members 14 and 20 by means of appropriate connections to the driving mechanism of the machine. The frame 62 has an extension arm 80 which carries in a hole at its free end a pin 82, the pin being securely held in place by means of a set screw 84. The rear end of the pin 82 is provided with a hole through which passes a rod 85 carrying at its upper end a collar 86 engaging the pin 82.

The lower end of the rod 85 is enlarged and slides in a bearing 87 which forms a part of the bracket 12. A spring 88 surrounds the smaller portion of the rod 85 and engages the collar 86 at its upper end. The tension on the spring 88 is adjusted by means of a nut 89 which determines the pressure to be applied to the upper and welt by the roll 52. The lower end of the rod 85 bears against the head of a stud 91 which is threaded into an extension 92 formed on the split sleeve 22. The frame 02 is returned to its normal position by the action of a spring secured to the pin 82 and to the machine frame. extension arm 80 is provided with an adjustable stop screw 94 which contacts with the arm 76 to limit the return movement of the frame 62.

A separator blade 95 is mounted adjacent to the tool 24 and the support 20 to prevent premature adhesion between the welt and the sole prior to the operation of pressing the welt and sole together. The blade 95 is mounted for sliding movement in the bracket 12 in such a manner that the blade is free to move in a plane vertical to the sole-engaging surface of the support 20. A pin 96 is secured to the upper end of the. blade 95 and extends through a slot 97 cut in the plate 15. The

The

separator blade is yieldingly held toward the support 20 by means of a plug which is pressed against the upper surface of the plate by a spring 99 and by another plug which is urged toward the blade by means of a spring 101, said plug engaging either one of two shallow recesses in the blade to hold it yieldingly in either its operative or inoperative position. The fact that the separator blade 95 is loosely mounted and is urged toward the sole=engaging surface of the support 20 by means of the springs 99 and 101 permits the blade to move with the support and thus prevents the blade from pullingaparttheportions of the shoe which have been previously cemented together. A bell-crank lever 98 is pivoted at 100 to the extension arm Y6, and the lever 98 is provided at its lower end with a slot through which the pin 96 passes. Vhen it is desired for any reason to remove the blade 95 from its position shown in F 3, it is onlynecessary to pull the upper arm of the lever 98 to the left (Fig. 3) the blade will be moved toward theright out of the path of feed of the shoe.

For feeding the work intermittently past the tool 14 and the support 20, feeding jaws 102, 104 areprovided. The jaw 102 has a shank portion 106 (Fig. 3) the lower end of which is secured b 1 means of screws 108 to the back of a slideway 110. The slideway 110 is pivoted at 112 (Fig. 4) to the machine column. The lower jaw 104 is secured to a slide 114 by a cap screw 116. The lower end of the slide114 is orlted for the reception of a spring 118 which normally urges the slide 114 and the jaw 104 upwardly towaro the jaw 102. The upward movement of the jaw 104. is controlled by a pawl-and-ratchet mechanism which is operated between feeding movements of the feed mechanism to force the jaw 104 downwardly away from the upper jaw. pawl-carrying arm 120 is pivotally mounted on the bearing 28 at 122. The free end of the pawl-carrying arm 120 has pivoted thereto at 119 a pawl 128 which has teeth on its lower end for engaging teeth on the lower end of the slide 114, the teeth being so formed that when the arm is depressed the slide 114 will be pushed down. The arm 120 also carries a retaining pawl 125 which is also pivoted to the arm 120 at 119 and has teeth in its lower end for engaging teeth formed in the side of the lower portion of the lower slideway 110, the teeth on the pawl and slideway being formed to permit downward movement of the pawl and arm and prevent upward movement thereof. The pawl 125 is normally urged toward the slideway 110 by a spring 121 which is located in recesses formed in the arm 120 and in the pawl 125, and a similar spring similarly arranged urges the pawl 123 toward the teeth in the slide 114. When permitted to do so,

lie

the spring 121 causes the pawl 125 to engage the teeth on the slideway 110 and the similar spring causes the pawl 123 to engage the teeth on the lower end of the slide. l Vhen the teeth of the pawl 125 engage the teeth in the slideway 110, the arm;120 is prevented from moving upwardly under the influence of a spring 127 but may be moved downwardly. An adjustable stop member 129 is secured to an outwardly extending lug on the bearing 28 and limits the upward movements of the arm 120 under the influence of the spring 127.

The pivoted slideway 110 is provided with an outwardly extending arm 124 (Fig. 4) to which is pivoted a rod 126. Up-and-down movements of the arm 124 cause the slideway 110 to be swung about its pivot 112 to approach and recede from the tool 14 and support 20. The lower end of the rod 126 is pivotally connected to an arm of a bell-crank lever 128 (Fig. 2) which is pivoted to a projecting portion of a bearing 31 in which a plunger 131 reciprocates to operate the post 26 through connections to be described hereinafter. The other arm of the bell-crank lever is provided with a curved cam slot 130 which forms a cam path for a roll secured to an arm 132 which is pinned to the post 131. As the post 131 is rcciprocated in the power operation of the machine, the roll on the arm 132 moves in the cam slot 130, which is shaped to impart through the bell-crank lever 128 the required up-and-down movements to the rod 126. The upper end of the rod126 has secured thereto a member 134 which carries an adjustable stop screw 135 arranged to contact at appropriate times with the lower surface of both pawls 123 and 125. The arm 124 is provided with an adjustable stop screw 136 which contacts with the upper surface of the pawl-carrying arm 120.

When the rod 126 is moved downwardly by the mechanism described, the stop member 136 on the arm 124 is moved toward the upper surface of the pawl-carrying arm 120 and during this interval the feed jaws 102, 104 are swung to the left. Further downward move ment of the arm 124 causes the adjustable stop member 136 to engage the upper surface of the pawl-carrying arm 120, swinging it downwardly so that the pawl 123, already released by the stop screw 135 and in engagement with the teeth on the slide 114, moves the slide downwardly and releases the lower jaw against the tension of the spring 118. At the same time the pawl 125 is released and its teeth slide past the teeth on the slideway 110 and prevent upward movement of the arm 120 during the firsu portion of the upward movement of the rod 126. V7 hen this upward movement of the rod 126 occurs, the stop member 135 does not immediately engage the lower surface of the pawl 125 because the ad- 65 justable gy is then spaced from the pawl. This first movement, however, serves to rock the slideway 110 on its pivot 112 and carry the jaws 102, 104 back to their position adjacent to the support 114 and the tool 20. Further upward movement of the rod causes the stop 134 to engage the lower surface of the pawl 125 and release its teeth from the slideway 110, permitting the arm 120 to be lifted against the stop 129 by the spring 127.

the pawl 123 and releases it from the slide 114, thus permitting the jaw 104 to be forced upwardly under the influence of the spring 118. The feeding jaws 102, 104 are thus operated automatically to clamp and feed the work, and after each feeding movement the jaws are returned to substantially their original position before the lower jaw is released to permit it again to clamp the work.

It is to be understood that since the shoe is made without a last, an upper a is cut by a suitable pattern to the exact size required for the shoe, a welt Z) of uniform width being sewed by stitches c to the edge of the upper with the edge of the upper and one edge of the welt flush with each other. A sole (Z is cut to the proper final shape and preferably a filler e is attached to the sole, the filler being of the same shape as the sole but smaller so that a uniform margin of the sole will be exposed about the periphery of the filler, the width of the margin being the same as that of the welt. This exposed margin is coated with cement, such as latex, as is also the lower face of the welt.

The upper and its welt are placed over the horn 53 with the inner surface of the upper adjacent to the welt in contact with the roll 52. The sole prepared as described is placed on the support 20 under the upper and the upper and sole properly located with respect to each other. The shoe is positioned with the welt under the tool 14 with its edge and the edge of the sole abutting against the gage 18; then, by operation of the treadle 48, the support 20 is moved toward the tool 14 and presses the sole against the welt.

The roll 52 forces the upper against the tool 14 and the gage 18 to cause the edge of the welt and the edge of the sole to be brought into alinement with each other. In this way the tool 14, support 20 and roll 52 co-operate to position the shoe parts and to press the welt against the projecting portion of the sole, the cemented surfaces being thus caused to adhere. This manual operation of the machine is of advantage during the preliminary stages of the operation to enable the upper to be located relatively to the sole.

To continue plete the securing of the shoe parts would, however, be very slow and fatiguing to the operator. With the present organization the operator can shift from manual operation to power operation of the machine by de- At the same time the stop 135 engages this manual operation to comshaft pressing a treadle 150. Thistreadle 150 fulcrumed at 151 (Fig. 1) held raised by a spring. A rod 153, connected at one end to the treadle 150, is yieldingly connected at its upper end by a spring 152 to one armof a bell-crank lever 155. the other arm of the bell crankto a detent 156 pivoted between ears formed on the lower end of the vertical shaft 131. 'By depression of the treadle 150 the detent 7 4 is swung over a continuously power-operated plunger 154. At its lower end to an eccentric strap mounted on an eccentric 158 (Fig. 2). The-eccentric is secured to a source of power such as an electric motor 162.

The vertical shaft 131 has a reduced upper portion which enters a bore in the lower end of the post 26. Surrounding the up-- per end of the reduced portion of the shaft 131 is a sleeve having an enlarged lower end 164 which rests on a spring 1676. This spring surrounds thereduced portion of the shaft 131 and rests" atits lower end in a cup like member 168 surrounding the shaft 131. The

sorin 166 resses at its u er end on the l e P PP enlarged lower end of the sleeve 164 which is held on the upper endof.tl1e reduced portion of the shaft 131 by a pin which passes through the shaft and through slots in the sleeve. The lower edge of the cup 168 rests on the member 132 and contact of the lower surface or the member 132 with the bearing 31 limits downward movement'of the shaft 131 in such position that the detent 156 will 1s in'its lowest position.

When the treadle 150 is depressed, the plunger 154 will engage the detent 156 and swing over the plunger 154 when the plunger force upwardly theshaft 131, the upperend of the reduced portion of the shaft will move in the bore in the lower endof the post 26 until the sleeve 164'engages the post, raised by the;

whereupon the post will be sleeve and, if the movement of the sleeve is arrestee, the spring 166 will be compressed. If there is work between the tool and support, a greater compression of the spring will occur. When the cam 38 is in its outward position, a full upward stroke will be given to the support 20 at each operation-of the eccentric. If desired, the operator may depress the treadle 48 to raisethe support 20 by the cam 38 to reduce the stroke of the support while the machine is power-operated.

The connections between the post 26 and the plunger 158 are the same as those described in my prior patent referred to above to which reference may be had for a more detailed description;

Although the parts of the machine have been described in detail, it'may be well to refer briefly to the operation of the machine, The shoe parts are placed in the machine, and

the machine is manually operated as described "A rod 157 connects the plunger 154' is pivoted 160 which carries connections to a nections,

' operation of the machine above to locate properly the prewelted upper relatively to the sole. In continuing the operation on the shoe by power, the treadle 150 is depressed, causing the detent 156 to move into the path of movement of the continuously driven plunger 154, thus connecting the power means to the shaft 162. The eccentric 158, through the above-mentioned connections, causes the work support 20 to be moved upwardly to clamp the welt or sole-attaching flange of the upper to the welt. When. the support 20 is moved downwardly, the feeding jaws 102, 104 engage the work and feed it to the left, as viewed in Fig; 2. At the end of the feeding movement, the lower feeding jaw 104 is moved downwardly by means of the pawl 123 on the pawl-carrying arm 120 and the stop 136 to release clamping pressure on the work. Thus, when the eccentric, through the conagain moves the work support 20 upwardly to clamp the work, the feeding jaws are caused to move toward the tool 14 and the support 20 and, when the jaws have nearly completed their return movement toward the tool, the stop 134 lower surface of the pawl 123, throwing the teeth on the pawl out of engagement with the teeth on the slide 114 which permits the jaw to clamp the work under the impulse of the spring 118. This completes one cycle of which will be continued as long as the treadle 150 is depressed. When the'operation has nearly been completed, the separator blade 95 is moved out of engagement with the sole and welt by swinging the handle of the bell-crank lever 128 to the left, as viewed in Figs. 1 and 3, thus pre venting the separating blade from pulling apart the portions of the shoe which have previously been cemented together.

It will be noted that the operation of the power means for moving the shoe support has no effect on the manual means for moving the support, these means being quite independent of each other as will be apparent from the detailed description in the above-mentioned Letters Patent No. 1,720,212. A

Although the illustrated machine has been shown and described as operating on a pres welted shoe, it is apparent that the machine :is not limited in its application to such a shoe but may be usedto operate on shoes of any other type wherein the upper is secured to the sole by a sole-attaching flange.
